A striking celestial event is set to unfold on Tuesday, as a total lunar eclipse will turn the moon a dramatic shade of red, often referred to as a “blood moon.” The eclipse will be visible across North and Central America, with observers in Australia and eastern Asia able to witness the spectacle Tuesday night. This total lunar eclipse is particularly noteworthy as it will be the last one until New Year’s Eve 2028, according to recent reports.
The phenomenon occurs when the Earth passes directly between the sun and the moon, casting a shadow that obscures the lunar surface. During totality, which is expected to last about an hour, sunlight is filtered through Earth’s atmosphere, scattering away most of its colors and leaving behind the reddish hues that give the “blood moon” its name. Understanding a lunar eclipse and its visibility can enhance the viewing experience for those in the path.
While a total lunar eclipse is a captivating sight, it’s a relatively relaxed astronomical event compared to a solar eclipse. “Compared to a solar eclipse, the lunar eclipse is a little more of a relaxed pace,” explained Catherine Miller, an astronomer at Middlebury College’s Mittelman Observatory. No special equipment is needed to observe the eclipse – just a clear, cloudless view of the sky. Astronomers recommend using a forecasting app or an online celestial calendar to pinpoint the exact timing for your location.
What Causes a Blood Moon?
The reddish color of the moon during a total lunar eclipse isn’t due to the moon itself changing, but rather to the way Earth’s atmosphere interacts with sunlight. As sunlight passes through the atmosphere, shorter wavelengths of light – blues and greens – are scattered away. Longer wavelengths, like reds and oranges, are able to pass through and reach the moon’s surface, giving it that characteristic reddish glow. This effect is similar to why sunsets appear red. The spectacle is a result of this atmospheric filtering process.
Who Will Be Able to See the Eclipse?
The visibility of the eclipse varies significantly depending on location. Those in North America, Central America, and the western portion of South America will have the best view of the total eclipse on Tuesday morning. Australia and eastern Asia will be able to observe the eclipse Tuesday night. Partial stages of the eclipse, where a portion of the moon is shadowed, will be visible from Central Asia and much of South America. Unfortunately, Africa and Europe will not have a view of this particular eclipse.
The eclipse follows closely on the heels of a “ring of fire” solar eclipse that occurred earlier this month in Antarctica, dazzling both researchers and the local penguin population. Solar and lunar eclipses are relatively common occurrences, with between four and seven happening each year, according to NASA. These events tend to cluster together as the sun, Earth, and moon align in their orbits.
Understanding Lunar and Solar Eclipses
Both lunar and solar eclipses are caused by the precise alignment of the sun, moon, and Earth. A solar eclipse happens when the moon passes between the sun and Earth, blocking the sun’s light. A lunar eclipse, as we’re seeing this week, occurs when Earth passes between the sun and moon. The orbits of these celestial bodies aren’t perfectly aligned, which is why eclipses don’t happen every month.
Astronomer Bennett Maruca of the University of Delaware notes that observers don’t need to be glued to the sky for the entire duration of the eclipse. “You don’t have to be out there the whole time to see the shadows moving,” he said. The changes in the moon’s appearance unfold over several hours, allowing for multiple opportunities to witness the event.
What’s Next for Lunar Eclipses?
For those who miss this total lunar eclipse, there will be another opportunity to view a partial lunar eclipse in August, which will be visible across the Americas, Europe, Africa, and western Asia. However, as noted, the next total lunar eclipse won’t occur until December 31, 2028, making this Tuesday’s event a particularly special occasion. Further details on eclipses in 2028 are available online.
The upcoming lunar events offer continued opportunities to observe these fascinating celestial displays. Retain an eye on space news and astronomical calendars for updates and viewing information.
